JULES LAGARDE, OF CLERMONT-FERRAND, FRANCE.

TYPE SETTING OR COMPOSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 757,319, dated April12, 1904.

Application iilell October 29, 1902. Serial No. 129,231. (No model.)

To cir/Z whom it may con/cern:

Be it known that I, JULES LAGARDE, a citizen of the French Republic,residing at Clermont-Ferrand, France, have invented certain seriesofperforations, the characters thus constituting the text to becomposed. The recordband can be produced in any suitable manner andparticularly by the machine or mechanism which forms the subject of aseparate patent application made by me on the'27 th day of July, 1901,Serial No. 69,951. Moreover, the mechanism constituting the machine ofthe present invention has beenv constructed as a result of a study ofthe mechanisms of said machine and the electric contact system whichforms the subject of my previous patent application, Serial No. 69, 950,filed July 27, 190.1.

The present invention is intended to assist the operator, who in theusual way operates the keyboard of the composing-machine, by theautomatic control of the keyboard and, as it has been previously stated,with the aid of a record-strip provided with the characters and signs ofthe text to be composed in the form of perforations, which in passingthrough the present machine, as hereinafter described, are adapted toproduce electric contacts and corresponding currents which respectivelyoperate the type setting and composing mechanism. Each character ortypographie sign corresponds to a particular combination of theseelectric contacts, this combination being such that the resultingcurrents act upon commutators of a special combination through" whichthey are transformed to a single current and directed according to thecombination to the electromagnet corresponding to the selected sign orcharacter of the settingmachine corresponding to the respective columnof perforations of the record-band..

The particular feature of the mechanism with which the record bandcoperates is called the reader and is preferably arranged upon theelectric contact mechanism under the control of the operator, so thatthe latter not only overlooks comfortablyand easily the mechanicaloperation, but also the text of the composition, so that he can effectcorrections by stopping the machine in case mistakes have occurred inthe previous transcription in the writing-machine above mentioned. Inshort, the operator can combine his mental ability with the mechanicaland rapid operation of the automatic mechanism.

In the accompanying drawings a construc-` tion of machine according tothis invention is given by way of illustration.

Figure 1 shows the whole arrangement of the mechanism in connection withthe electric contact-board, as described in application Serial No.69,950, of 1901, and the automatic reader and winder for the perforatedand printed control or'record strip supported by a band-carrier to theright of the electric contact device. These parts are electricallyconnected with one another and with a multiplying apparatus. Fig. 1u isan elevation of the band-car'- rier. Fig. 2 is a plan view of theautomatic reader. Fig. 3 is a side view ofthe Winder.

Fig. 13 is a planview of this device. Fig. 14 is a diagram showing the circuitconnections of a complete apparatus.

The record-strip, which is perforated and printed by any suitablemachine, passes into an automatic reading apparatus. This automaticreading apparatus (shown in Figs. 1 and 2) is secured upon a base 101 ofthe electric contact device above the character-board 102 under thecontrol of the operator, so as to enable the latter to strike at aconvenient Inoment with his stylus 97 one or the other of the blocks'ofthe board 102 in order to act independently from the automatic operationof the mechanism upon the keyboard of the composing-machine, so as tocorrect any mistakes which may occur in the perforated band. Thisreading apparatus consists of a frame 104, secured by a support 103 uponthe platform 101, between the ianges of which are arranged rollers 105,106, 107, 108, 109, 110, and 111, which serve as a guide to theperforated record-strip 100. The cylinder 108 is of insulating materialand is surrounded by a conductive sleeve which forms part of the circuitof an electric generator 99 through a spring 112, fixed upon aninsulating-support of the frame 104 and bearing against the periphery ofthe cylinder 108. The roller 109 is covered with yielding material andinsures through the pressure of the bearing-springs 113 of itscorresponding roller 110 the passage of the band 100 through themachine. The roller 109 for moving the band 100 is driven by a ratchet114, fixed on the shaft of theroller 109 and actuated by a pawl 115,resiliently mountedupon a lever 116, pivoted at 117 on the frame 104 andnormally drawn down by a spring 118. At the opposite end the lever 116forms an armature 119, Which coperates with the core of a doubleelectromagnet 120. A fiat spring 121, iXed on the armature 119, acts incombination with a set-screw 122 as an ordinary trembler under themagnetic action of the electromagnet 120. The current flowing from thegenerator 99 to the stylus 97 passes through the block 127 to theelectromagnet 120 and from the latter tothe insulated support 123 of thescrew 122 and returns through the trembler 121 to the generator. It isevident that the current could flow in the opposite direction. The band100 thus drawn from right to left on passing over the roller 108 passesunder and in contact with a series of contact-ngers 124, in this caseseven in number, secured independently of each other upon across-bar125, of insulating material, fixed to the frame 104. These fingers,which could be replaced by conductive spring-contacts, are connectedseparately by corresponding contacts 126 to the multiplier mechanism,which wwwY will be hereinafter described and is particularly representedin Figs. 10 to 13. The ends of the fingers 124 which rest above thecylinder 1 28 are brought in contact with the jacket of this cylinderwhen the perforations in the band 100 present themselves beneath theends of the fingers 124.

The working and the resting of the readingA should begin with thebeginning end of the band, that the latter should be drawn out from thecenter of the coil. To this end the band 100, after its having' beenwound on the drum on the record-making machine and after the operatorhas made several windings of blank band in order to avoid tearing of theprinted portions, is disengaged from the drum and placed on aband-carrier specially adapted for this purpose and shown in Figs. 1, 8,and 9. This carrier consists of a horizontal triangular support 130 andis secured to the main frame of the composing-machine by an extension orby a bracket. Upon this support 130 is mounted a disk 131, the shaft 132of which extends through the support 130 and turns at its lower end in abracket 133, secured to the support 130. This disk 131 is provided withfour radial grooves 134, in each of which slides an angle-bar 135, whichcan be secured at any convenient point by a screw 136. The verticalparts of the bars 135 are of a sufiicient height to serve as a supportfor the roll and are preferably of semicircular or arc-shaped form. Ateach end of the support 130 is a standard 137, to each of which is fixedwith a limited motion a horizontal lever 138, carrying a roller 139,which is arranged above the disk 131 toward the center of the latter.One of the levers 138 carries, moreover, a fork 140, in which turns ahorizontal roller 141.

In order to place the perforated recordband on the carrier, the levers138 are raised and the roll is placed upon the disk 131 by inserting itbetween the plates 135. The levers 138 are then turned down and theirrollers enter the space previously occupied by the hub of the Winder.The band is then drawn out by the end in the center of the roll andguided over the roller 141, which directs it horizontally toward theautomatic reading device. The diameter of the internal opening of theroll on the band-carrier grows as the band is unwound in the sameproportions as the diameter of the roll, which is formed on theWinding-drum, so that the rotation of TOO IIS

the latter and of the band-carrier can be synchronously controlled, aswill hereinafterl be explained.

The rotation of the disk 131 is effected by a ratchet 142 on the shaft132 of the disk and driven by a spring-pawl 143, mounted on a lever 144,which is pivoted at 145'to the support 130. This lever 144 forms withits extremity opposite to the pawl 143 an armature 146, which cooperateswith the cores of a double electromagnet 147, suspended from the support130. A spring 148 draws the lever 144 after each attraction of theelectromagnet 147 back to its initial position. A post 149, iixed to thesupport 130, carries an adjusting-screw 150, which allows of lengtheningor shortening the throw of the pawl 143 to cause it to move back over alarger or smaller number of teeth, whereby the speed of unwinding of theband is regulated.

The band 100 is upon leaving the automatic reader wound on abobbin.-(Shown in Fig. 1 to the left of the reader and `in side viewin Fig.340i' the drawings.) This Winding-drum is supported by a frame 151, thebase of which has the same inclination yas that of the platform 101 ofthe electric contact device. The drum consists of two disks 152 and 153,turning about an axle 154, one end of, which rotates on thecentering-point of an adjustingscrew 155, Varranged in an adjustablebracket 156, which is xed to the frame 151 by a screw 157, pins 158maintaining the bracket 156 in its position precisely adjusted withregard to the other bracket tixed to the frame 151. The center of thedrum, between the two disks 152 153, is formed byan expansible hub onwhich the band is wound from the reader.v This hub is constituted by twohalves 159 160, which when connected form aV cylinder the diameter ofwhich can when required, be reduced, so as to allow of an easy removalof the band. One of the parts, 159, is xed onthe disk 152, while theother part, 160, is movable to and from the other and is attached to thedisk by "pins 161, which engage-in grooves or slots 162 and guide thepart 160 in its movement. A spring or trap 163, bearing with its endsagainst the part 159 and with-its center against the part 160, tends tomaintain the two halvesv apart from one another, sof vas to form withtheir external circumferences a' cylinder of the maximum dimensions, theoutward movement of the halt' 160 being limited by the pins 161 in theslots 162. The compression of the springs 163 in order to allow the twohalves to approach each other is effected by a fork 164, the prongs ofwhich press against the springs 163. This fork is operated by a cam 165,acting against its raised edge 166. The shaft of thecam 165 serves as aguide for the fork 164 andis provided with a handle which allows of itsoperation. Byacting through 'the cam 165 upon the spring 163 in order toallow the approach of the two parts 159 160 to the generator.

time loosened, so that the roll can then be removed. The winding of theband onto thev drum is effected by the action of a double electromagnet168, mounted on a bracket 169 0n the frame 151, and an armature 170, onwhich is mounted a small electromagnet 171. This armature is attached tothe extremity of a lever 172, which is Apivoted on the bracket 169 andcarries toward its other end a pawl. 173, engaging with a ratchet-Wheel174 on the axle 154 of the disks 152 153. A lug 175 on the lever 172bears under the action of a c-ounterweight 17 6, mounted at the end ofthe lever V17 2, againsta flexible blade 177, fixed to an insulatingpart carried by the frame 151. On yielding this blade 177 makes contactwith the central point of an adjusting-screw 17 8, which is carried by abracket 179, fixed to the frame 151.

i The current coming from the generator 99 flows to the bracket 179 andscrew 178 and passes through the blade 17 7 when the latter is incontact with the screw 17 8, thence thro ugh the armature-coil 171 andmagnet 168, after which it passes through the double electromagnet 147of the band-carrier and from here The respective coils 168 and 147 ofthe Winder and of the band-carrier are thus switched in one circuit, andtheir motions therefore take place ina synchronous manner. When thelever 172 by the action of its counterweight 176 causes the blade 177 tomake contact with thescrew 178, the circuitis closed, and the coils 168and 147 are energized, so as to attract the respective armature-levers144 and 172, and consequently effect the rotation of the disk 131 of theband-carrier and oi' the disks 152 and 153 of the winding-up drum. Inoscillating, the lever 17 2 leaves the blade 177, which in its turn isseparated from the screw 178 and breaks the circuit. The current thus nolonger passing through the coils allows the levers 142 and 17 2 tooscillate in the reverse direction, andthe lever 17 2 comes in contactunder the influence of its weight 17 6 with the blade 17 7 in order toclose the circuit, and consequently to produce another operationsimultaneously with the rotations of the disks of the band-carrier andthe winding. The band thus transported from the band-carrier to the drumon passing over the reader never travels a longer distance than thatallowed by the release oi. the cylinders of the reader, and consequentlythe drum will only wind up a length of the band determined by IOO Fig.1, the function of which consists in distributing between the variouscontacts of the electric controlling apparatus the current which causesthe function of each of the keys when the corresponding electromagnet isbrought automatically into the circuit of the current of the generatorby the series of perforations of the band. This multiplying apparatus isshown in Figs. 10, 11, 12, and 13 and comprises a series of commutators,in this case seven in number, and each comprising a variable number ofcontacts. v In order to simplify the explanation which follows, thesecommutators are designated with the numbers I to VII, as shown in Fig.10. Each commutator consists of two standards 181, mounted upon abase-plate 180, which serves as the base for the whole of thisapparatus. At their upper parts these standards 181 carryadjustingscrews 182, between the points of which a wooden bar 183 ismounted, to which are screwed plates or blades 184, the number of whichvaries for each commutator according to the combinations required.Transversely to and at the center of the bar 183 is a lever 185, one endof which carries an armature 186, which coopera-tes with anelectromagnet 187. The other end of the lever 185 is connected to aspring 188, which tends to press the armature 186 against a set-sc rew189, screwed into `a support 190. The lower ends of the blades 184 liebetween two series of other plates 191 192, which are arranged,respectively, for each series in equal number to the blades 184 uponbars 193 and 194, secured to the base 180. When no current passesthrough the electromagnet 187, the lever 185, acted upon by the spring188, tends to maintain all the blades 184 pressed against the plates 192on the right of the commutator.

The electric connection between the commutators is eected throughcontacts or terminals 195, arranged upon the base 180 of the apparatusin numbers equal to those of the contact-blades 184 of each commutator.Above the contacts 195 is arranged a bar 196. carrying othercorresponding contacts 197, which are bent so as to produce a resilientaction in order to insure the connection. A Hexible wire connects eachcontact 197 with the corresponding blade 184 on the movable oroscillatory part of the commutator. The electric connection of the othercontacts of the commutator is effected in the manner indicated, forinstance, for some of them in the drawings. This connection will beeasily understood if it is noted that the wires are successivelyconnected from one commutator to the other through'their respective endswith the plates above which are indicated the correspondingreference-numbers. The characters, numerals, or signs situated near theplates of the commutators VI and VIIindicate the points from which theparticular current flows to each of the said characters, nu-

merals, or signs, the direction of which is given by the action of thecommutators. The

various oscillations or combined motions of the iingers 124 of thecurrent from the generator. The feed-wire of this current is connectedto a circuit-breaker adapted to cause lthe break-spark to be' madealways at the same point in order to avoid the destructive eifects uponthe contact-plates of the commutators. This break device (represented inFigs. 12 and 13) consists of a bracket 198, to which is connected by aspring 199 an armature 200, cooperating with a double-actingelectromagnet 201. This armature 200 bears under the action of thespring 199, against an adjustable screw 203, fixed to another bracket204. Another adjustable screw 205 is situated opposite to the screw 203on a bracket or arm 204 and faces vthe contacts 202 of the armature. Thescrew 205 is connected through thev bracket 204 to the wire whichsupplies the current from the generator. This current passes through thescrew 205 to the armature 200 and to the support 198, from which itpasses to the blade 184 of the commutator I, from whence it takes acourse, as indicated,I through the various commutators controlled by thereader. The current which passes through the electric contacts of theVseven commutators is connected by a common wire to the electromagnet201 in such a manner that each time when one or more commutators are inaction the current iniuences the said electromagnet and attracts thearmature 200.

The contact-blades 164 of the commutators are very flexible, so thateach time an attraction of the lever 185Y takes place the blades 184will bend at their centers, (commutator VII, Fig. 11,) so that when thecurrent of the commutators is broken and the spring 188 returns thelever 185 to its former position the blades 184 remain with their endsfor a moment in contact with the corresponding contacts 191. Though thiscontact of the blades 184 and 191 will be of very short duration, thisperiod of contact nevertheless eX- tends beyond that which is necessaryfor breaking the current between the two contact-points Aformed by screw205 and the armature 200,

and thereby protects the parts against spark destruction. The extent ofmovement or position of the armature 200 is regulated at will by thescrews 203 and 205. f

The various contact-plates -191 192 of the commutators VI and VII, Fig.10, in front of which are indicated their typographic characters orsigns, are connected to the terminals of the electric keyboard byinsulating-bars 206, Fig. 1, fixed by brackets 207 tothe lateral wallsof the frame 101. carry on their inner sides as many blades 208 as thereare electric terminals on the board. The

IIO

These bars 206 Y wires of these contacts make contact with the blades209, against which bear other blades 210, which are in connection withthe blocks of the contact-board 102.

The brackets 207 are secured to the base of the board by screws 211,which effect, by being tightened or loosened and by the separation ofthe bars from the board, the connection or disconnection between themultiplier and the contact device. Other screws 212 allow of thelongitudinal displacement of the bars 206 with regard to the base 101,so as to position the contacts 208 and 210 relatively to one another.

The strip on being unwound allows, with the aid of the reading deviceand by means of the contact-lingers 124, corresponding to theperforations in the strip, as abovedescribed, of

the passage of the current to the corresponding contacts of themultiplier, in which through the contact-plates 191 and 192 the currentfor the contacts of the electric board receives its has been brought incontact by the attraction ofA the corresponding electromagnet 187. Fromhere the current iiows without reversal through the conductor 2 to thecommutator II and leaves the latter through the contact 192, enters thecommutator III, from which it passes by inversion to 6 and by a secondinversion travels to 14 of the commutator IV and to this number in thecommutators V and VI, which are inoperative, and by inversion to thecommutator VII, which it leaves through the corresponding contact-plate191, which bears the indication '1. This action will be the same for allperforations which travel through the reader and which, according totheir combination, act independently of one another upon thecommutators, so as to direct the current toward the acting magnet of theelectric device corresponding to the characters which are represented bythese perforations.

It will now be easily understood that with the apparatus above describedthe operator need only watch the unwinding of the perforatedrecord-strip in the reader and constantly press the stylus 97 upon thebutton 127, so as to allow, with the aid of the current from thegenerator 99, the various actions of the parts of this mechanism to takeplace and their combined action upon the electromagnets, which can bearranged above the keyboard of a typecomposing machine or brought indirect connection with the levers operated by the keys.

If a mistake occurs through the wrong character being given on theperforated strip, the operator need only raise the contact-fingers 124in any convenient manner-for inst-ance, by a single armature attractingthe whole set of fn'gersand touch with his stylus the correct block onthe contact-board. Upon returning the stylus 97 to the block 127 thedrawing-drum will move forward the band to the necessary extent so as toleave out the incorrect perforation, after which the contactfingers onbeing lowered again allow the reader to continue its mechanicaloperation.

Insulated blocks 213 214 are arranged on the base 101 lof the board inorder to enable the operator by touching one or other of these blockswith his stylus'to operate or to stop or start the mechanism `of thetype-composing machine at will.

When desired, instead of all the circuits of the complete apparatusbeing connected to. a single generator, as above described, independentbatteries may be employed, and such an arrangement is showndiagrammatically in Fig. 14. In this arrangement the electriccontact-board 101 supports the reader 104, through which passes thepaper band 100 Afrom the unwinding-roller 130 to the winding-up roller151 and which the operator operates by means of a style 97 to actuatethe keyboard of al type-setting machine. The contacts of thiscontact-board are connected by connections, Yhereinafter explained, tothe multiplicator 180the object of which is to guide by inversions thecombinations of electric impulses toward one of the outlet-blades 191 or192 of the said multiplicator, said blades being respectively connectedby contact-blades 208 209 to the various electromagnets 50, arrangedeach opposite one of the keys 51 of the keyboard of the type-settingmachine. The connections between the various parts are as follows: Thestyle 97, held by the operator, is arranged in the circuit of a battery52, from which it receives current by means of a wire 58, so that whenthis style constantly rests on the key 127 the current passes throughthe wire 54 and actuates the eleetromagnet 120 of the reader 104 andfrom thence returns through wire 55 to the battery 52. The trembler 119of the reader, thus actuated by the electromagnet 120, acts in acontinuous manner on the roller 109 in order to effect the supplying ofthe perforated band. The positive pole of the battery 52 is alsoconnected by a shunt-wire 56 from the wire 54 to the metal cylinder 108,against which rest the seven brushes 124, which come, respectively,opposite to the seven series of holes which in the example illustratedconstitute the various combinations of the perforated band. Each of thebrushes 124 is connected by a wire 57y to one of the commutators I, II,III, IV, V, VI, and VII of the multiplicator. 180, and the return-wiresof these commutators are connected by a single conductor 58 to thebattery. By being placed in contact with the blades 191 or 192 IOO IIO

the blades of the commutators direct the current of the battery by awire 59, connected to a commutatorI, (according to the inversionseffected and corresponding to the combination of the perforations of theband that may come under the contact-brushes 124 of Vthe reader,) towardone or the other end blades 191 or 192. These blades 191 and 192 of themultiplicator are respectively connected by wires 61 to blades 208 ofthe contactboard, which are in their turn in contact with the blades209, coupledl by wires 62 to the electromagnets 50, which act on thekeyboard of the setting-machine, and from these the circuits arecompleted through a single conduit 63 to the battery 60.

The circuits of the unrolling and the rewinding mechanism for theperforated band 100 are as follows: A battery 64 is connected by a Wire65 to the contact 179 of the windingup drum, and thecontact is connectedto the electromagnet 168 intermittently by the pivoted lever 172, saidlever being operated by the magnet 168 in one direction and in theopposite direction by a counterweight and during its movement acting, bymeans of a pawl 173, on the said drum. From the electromagnet 168 thecircuit passes by wire 66 through the magnet 147 of the unwinding drum(which is thus started simultaneously with the winding-up drum) and fromthence by wire 67 to the battery 64.
